Embodiment Construction
[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0020] Such as figure 1 As shown, an energy-saving air-cooled meshless hot-cutting die head for recycled plastic extrusion, including a die head body, the inside of the die head body is divided into a die head outer cavity 1 and a die head inner cavity 2, and the die head inner cavity 2 A slag discharge screw 3 is installed in the middle, and a filter sleeve 4 is arranged on one side of the feed end of the inner cavity 2 of the die head. One end of the filter sleeve 4 is connected with a slag discharge chamber 5 for storing impurities. The end is connected to the slag discharge door 6, and the impurities are pushed out through the slag discharge screw 3. A high temperature resistant pressure sensor is installed in the slag discharge door 6, and ...

The invention discloses an energy-saving air-cooled net-free hot cut mold head for reclaimed plastic extrusion. The mold head comprises a mold head body, wherein the inside of the mold head is divided into an outer cavity and an inner cavity; a slag discharging screw is arranged in the inner cavity; a filter sleeve is arranged at one side of the feeding end of the inner cavity; a slag discharging cavity is connected with one end of the filter sleeve and is used for storage impurities; no micro-pore is formed in the inner wall; the outer end of the slag discharging cavity is connected to a slag discharging gate; the impurities are pushed and discharged through the slag discharging screw; a high-temperature resistant pressure sensor is arranged in the slag discharging gate; filtering micro-pores are formed in the filter sleeve; the slag discharging screw is transmission by a screw rod and is used for pushing melted plastic and scraping the impurities on the inner wall of the filter sleeve to the slag discharging cavity; an extrusion opening is formed in the outer cavity; a circular template is arranged at the extrusion opening; thick holes are fully and uniformly distributed in the circular template; the surface of the circular template is smooth; a rotating cutter is arranged at the outside of the circular template; a cutter blade is tightly attached to the outlet of the circular template, and the rotating area covers the whole circular template.
Description
technical field [0001] The invention relates to the technical field of plastic processing equipment, in particular to an energy-saving air-cooled meshless hot-cutting die head for recycled plastic extrusion. Background technique [0002] With the development of industry, the application of plastic products has spread all over the fields of industry, agriculture and daily life. The waste plastic waste generated every day in the world cannot be estimated, but it is obvious that it has a great pressure on the environment. In order to deal with these plastics Garbage, the current method is generally landfill, incineration and so on. However, due to the long natural degradation time of ordinary plastic waste, it usually takes more than a hundred years to degrade, and a large amount of methane and other harmful substances will be produced during the degradation process, so the landfill method has been criticized by many experts; while incineration Harmful gases and smoke generate...
